I guess that's it then. Almost always when the characters collide with something fast enough for them to explode, the game starts lagging big time, so I have to restart.

Hitting an impact explosive with a jetpack tends to lag.

There's an option to make the map wrap around horizontally and/or vertically in scenes.ini, but the game only supports the current mode. Alone the "seam" where the level repeats, stuff like the health and weapon indicators above your character start disappearing. It also erasesthe 3 red pixels that appear when you go into sharp and aim across the X-wrap.

Damn you X Wrap *shakes fist in anger*

And theres a fix for the engine bug in the mods section somewhere.

this is the damn digging thing that sucks so much! (I like to make my brain invincible )
